  <div>
   <p id="fc_gud_0019_0__p10332144917542">Before performing backup, you need to associate the resources to be protected with a specified SLA. The system protects the resources and periodically executes backup jobs based on the SLA. You can perform a backup job immediately through manual backup.</p>
   <div class="section">
    <h4 class="sectiontitle">Precautions</h4>
    <ul>
     <li>During manual backup, the parameters (except <span class="uicontrol"><b><span><strong>Automatic Retry</strong></span></b></span>), such as <span class="uicontrol"><b><span><strong>Rate Limiting Policies</strong></span></b></span>, <span class="uicontrol"><b>Job Failure Alarm</b></span>, and <span class="uicontrol"><b><span><strong>Source Deduplication</strong></span></b></span>, that are defined in the SLA are applied to the manual backup job.</li>
     <li>Copies generated by manual backup are retained for the duration defined in the SLA.<p>If the protection policy selected during manual backup is not defined in the SLA, the generated backup copy will be retained permanently. If <span><strong>Forever Incremental (Synthetic Full) Backup</strong></span> is not defined in the SLA but <span><strong>Forever Incremental (Synthetic Full) Backup</strong></span> is selected during manual backup, copies generated by the manual forever incremental (synthetic full) backup will be retained permanently.</p></li>
     <li>If a replication or archive policy has been defined in the SLA, the system will perform replication or archiving once based on the SLA when you perform manual backup.</li>
    </ul>
   </div>
   <div class="section">
    <h4 class="sectiontitle">Prerequisites</h4>
    <ul>
     <li>If you want to back up data when the VM is started, ensure that Tools has been installed on the VM. Otherwise, backup cannot be performed. For details about how to install the tool, see the <span>FusionCompute online help</span>.</li>
     <li>For FusionCompute 8.7.0 and later versions, if you want to use an independent backup network plane for LAN-based backup and restoration, configure an independent backup network plane through FusionCompute first. For details, see <a href="fc_gud_0079.html">Configuring the Backup Network Plane (Applicable to FusionCompute 8.7.0 and Later Versions)</a> (applicable to only 1.6.0 and later versions).</li>
